OS/360 would like a word...

Is it actual binary compatibility? Or it is something higher-level?

(to be honest going from DOS to Windows is a different problem, though that doesn't justify the atrocities shown in the document :) )

They do have a binary backward compatibility date sometime in the 1960s, possibly 1964.

But from what little I remember from my intro-to-mainframes day at big blue many years ago, I think it's like some sort of multi-layered emulation now, to run code that's that old. But your "Hello World" program built on OS/360 released in 1964 will still run on modern Z/OS, or so I'm told.

Of course they're not desktop systems! (I'd hate to see the desk...)

Well, with Hercules you could do :)

But no, as I said below, I'd hate to see the desk!
